ToolCall.tsx previously imported highlight.js statically, pulling the
entire hljs bundle into the main Chat chunk and preventing Vite from
splitting it into the lazy markdown chunk.
Now hljs is dynamically imported and loaded on first use. This:
- Removes the Vite build warning about mixed static/dynamic imports
- Reduces the Chat chunk by ~1.6 KB
- Consolidates hljs into the lazy markdown chunk
- Renders unhighlighted text instantly, then re-renders with syntax
highlighting once hljs loads (typically < 100ms)
- Add copyToClipboard utility with execCommand fallback for HTTP deployments (#76)
- Replace all navigator.clipboard.writeText calls with copyToClipboard
- Session rename now persists server-side via sessions.patch (#78)
- Pass onRename callback from App to Sidebar
- Replace div with <main> for primary chat pane (screen reader landmark)
- Replace div with <section> for split pane
- Add skip-to-content link for keyboard navigation (Tab → jump to chat input)
- Add aria-expanded and aria-label to tool call badge buttons
- Add id='chat-input' to textarea for skip link target
- Add i18n keys for new ARIA labels (EN + FR)
- Expose resolvedTheme in ThemeContext for theme-aware rendering
- Tool call badges: darker text colors and higher bg opacity in light theme
- User message bubbles: increased bg opacity and border strength in light theme
- Progress bars and send button already use accent CSS variables (no change needed)
Closes feedback #60
- User messages appear instantly with 'sending' state (dimmed, clock icon)
- Transitions to 'sent' (checkmark) when server acknowledges
- Shows error state (alert icon, retry visible) if send fails
- Applied to both primary and secondary sessions
Replace highlight.js/lib/common (36 languages) with a curated subset
of 16 languages relevant for coding-assistant chat UIs. Both ToolCall
(direct hljs) and ChatMessage (rehype-highlight) now share the same
custom bundle from src/lib/highlight.ts.
Languages included: bash, css, diff, dockerfile, go, ini, javascript,
json, markdown, python, rust, shell, sql, typescript, xml, yaml.
Markdown chunk: 477KB → 336KB (-30%, -45KB gzipped)
Suppress 3 react-hooks/set-state-in-effect warnings with targeted
eslint-disable comments. These are intentional patterns:
- ChatInput: restore draft text on session switch
- MessageSearch: reset active index on query change
- ToolCall: sync open state with global collapse/expand toggle
Lint now passes with 0 errors and 0 warnings.
Replace ~150 hardcoded Tailwind color classes (bg-zinc-*, text-zinc-*,
border-white/*, text-cyan-*, bg-cyan-*) with CSS custom properties
(--pc-*) across all 17 components.
Add @theme block in index.css for Tailwind v4 theme-aware utility
classes (bg-pc-elevated, text-pc-text, border-pc-border, etc.).
Add --pc-hover, --pc-hover-strong, --pc-separator variables per theme
(white/alpha for dark/OLED, black/alpha for light).
Theme switcher (dark/light/OLED) now actually works — all UI elements
respond to theme changes in real-time.
Fixes#55
- Extract ThemeContext and ToolCollapseContext definitions into separate
files to satisfy react-refresh/only-export-components rule
- Move useTheme and useToolCollapse hooks to dedicated hook files
- Fix empty catch block in ThemeContext (add comment)
- Replace Date.now() ref in ThinkingIndicator with useState initializer
- Update all imports across components
Closes feedback #58
- Add ThemeContext with CSS custom properties for all base colors
- Three theme modes: Dark (default), Light, OLED Black
- Six accent colors: Cyan, Violet, Emerald, Amber, Rose, Blue

- Persisted in localStorage
- CSS variables replace hardcoded hex colors in index.css and components
- i18n support (EN/FR) for theme labels
Add a wrap/nowrap toggle button on tool call parameters and results.
Default: word-wrap enabled (pre-wrap + break-words) so content fits
without horizontal scrolling. Click the toggle to switch to nowrap
mode for raw formatting with horizontal scroll.
Closes feedback #41
Adds a floating button in the chat area that lets users collapse or expand
all tool call details at once. Useful for long conversations with many tool
calls where scrolling through expanded results is tedious.
- New ToolCollapseContext provides global collapse/expand state
- ToolCall components react to global state changes via version tracking
- Toggle button appears only when conversation has tool calls
- Supports EN/FR i18n
- Add GatewayMessage and JsonPayload interfaces to gateway.ts
- Type WebSocket message parsing with GatewayMessage instead of any
- Use ReturnType<typeof setTimeout> for timer refs
- Type chat event payload destructuring explicitly
- Add ChatPayloadMessage interface for extractText()
- Replace any casts in loadSessions/loadHistory with typed assertions
- Add str() helper in ToolCall.tsx for safe unknown→string extraction
- Use Extract<MessageBlock, ...> type guards instead of `as any` casts
- Type CodeBlock children prop properly
- Add image block type for base64 and URL images
- Parse image/image_url blocks from gateway history
- Render images inline in chat messages (rounded, dark-themed)
- Click-to-zoom lightbox with Escape to close
- Markdown images also use the lightbox component
- Detect base64 images in tool results (e.g. Read tool on image files)
- Support png, jpg, gif, webp formats
- Lightweight i18n system in src/lib/i18n.ts (no external deps)
- All UI strings extracted to translation keys
- English (default) and French locales included
- Set VITE_LOCALE=fr in .env for French UI
